Telescopic Luggage Handle Stabilization to Reduce Wobble
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telescopic handles in luggage are unstable due to clearances between inner and outer handle elements, leading to wobbling and undesired movement.
Innovation Solution
A stabilizing device is introduced, comprising an inner and outer stabilizing element that creates a frictional connection with the handle elements, providing pre-tension to stabilize the inner and outer handle elements relative to each other, thereby reducing or preventing wobbling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If clearances are provided between inner and outer handle elements to allow telescopic movement, then the handle can expand and retract smoothly, but the arrangement becomes unstable and wobbling occurs
Solution Approach 1:
A stabilizing device is introduced as an intermediary component between the inner and outer handle elements. This device includes a device body with an opening and stabilizing elements that extend radially to contact both the inner handle element (through the opening) and the outer handle element (on the outer surface), thereby mediating the interaction between the two handle elements and preventing relative wobbling while allowing telescopic movement
Solution Approach 2:
The stabilizing device is nested within the telescopic handle structure, with the device body positioned between the inner and outer handle elements. The inner stabilizing element extends through the device body opening to contact the inner handle element, while the outer stabilizing element contacts the outer handle element, creating a nested arrangement that stabilizes the telescopic mechanism
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The stabilizing device effectively reduces wobbling and tilting of the handle elements, ensuring stability and smooth operation of the telescopic handle while allowing for expansion and retraction.
Implementation Method 1
The inner stabilizing element and the outer stabilizing element are configured such that, in an installed position, the inner stabilizing element acts on the inner handle element and the outer stabilizing element acts on the outer handle element
